ABSTRACT:
A variable inductor includes at most one coil of electrically conductive material and at most two distinct, separately formed portions of magnetic core material positioned to conduct magnetic flux resulting from passage of electrical current through the coil. At least one of the portions of magnetic core material is located at least partially within a space surrounded by the coil and is movable with respect to the coil. A control device is attached to the movable portion of magnetic core material in a manner such that the movable portion can be moved in its entirety, by manipulating the control device, to change the configuration of a gap within the space surrounded by the coil and defined in part by the movable portion, to vary thereby the inductance of the coil.
